Derived from the Japanese word "Kankokujin" (pronounced Kahn-koe-koo-jin) , meaning "Korean". Typically used as an insulting slur to reffer to a korean person. Unlike other racial slurs like "nigger", koreans are for the most part unaware of the meaning of this word and will thus not take offense when it is mentioned in front of them.

Korean: *Walks away unoffended and unpreturbed*
